Abstract
An apparatus includes a calculation unit configured to calculate a target correction amount based on a shake, a stabilization control unit configured to provide control on driving of a sensor in a direction intersecting an optical axis of a pickup optical system, based on the target correction amount, an autofocusing control unit configured to provide control on focusing based on an image signal output from the sensor, and a setting unit configured to set a limit value for the target correction amount based on a characteristic of the pickup optical system and focusing accuracy of the autofocusing unit. The setting unit is configured to change the limit value depending on the pickup condition, and is capable of setting a first limit value based on the characteristic and a second limit value based on the focusing accuracy.
